10 AM – Intro To Java

Today We Do

1. We continued our EmailApplication project. We added the ability to create new email and check inbox feature.
2. Also when we create a new email, we check if the email entered exists in our system.

Homework

1. Inside EmailApplication, add code to enable “3. List all Email Accounts” . All email accounts now is stored inside HashMap, but you have not learned how to go through all elements inside HashMap yet. This is what you need to do:

   1. // Instead of 
      for(EmailAccount acct: accountMap) {
         // do your code
      }
      
      // you need to do the following instead
      for(emailAccount acct: accountMap.values()) {
         // print email and name from acct
      }

2. Inside SchoolApplication, when you try to find student by HashMap, you will get an error when trying to find a student that does not exists in our system. Add code so when student does not exists, the system will print “<student name> does not exists in our system”.
